9. Equal weights of methane and oxygen aremixed in an empty vessel at 298K. Thefraction of the total pressure exerted bymethane is : |
|
Answer» Sol. If x g of both oxygen and methane are mixed then : Mole of oxygen = x/32 Mole of methane = x/16 ⇒ mole fraction of oxygen = (x/32)/(x/32 + x/16) = 1/3 According to law of partial pressure Partial pressure of oxygen (po2) = mole-fraction × total pressure ⇒ 〖Po〗_2/p = 1/3 |
